Media scholars as well as the public frequently use the terms âmass communicationâ and âmass mediaâ, but the meaning of these terms is often ambiguous. While it is assumed that everyone knows what these terms mean, the few scholars who attempt to define these terms struggle to capture the essence of their meaning without including elements that are faulty, and this task is becoming even more difficult in the new media environment. We are left with the troubling question: What are the âmassâ media? This review constructs an answer to this question in a four step process. The first step features a critical analysis of the literature to identify definitional elements used by scholars. These definitional elements are subjected to four screens that evaluate their utility in a second step. The third step adds elements missing from the literature so as to make the eventual definition more useful in the new media environment. Finally, the fourth step features the construction of a working definition of âmassâ media.
